Question

3. Find the value of x and y in the following figure.
​

Answer 1

Answer:

In the given figure,

y = 90° [Vertical opposite angles]

x = 45° [As shown in figure, the two angles is same meas x, and we know that sum of all angles in a triangle is 180°. Hence, both value of x will be same]

Answer 2

Step-by-step explanation:

y=90 degree (opposite angles are equal)

therefore, x+x+y=180 (sum of 3 angle of a triangle is 180 degree)

2x+90=180

2x=180-90

2x=180-902x=90

2x=180-902x=90x=90/2

2x=180-902x=90x=90/2x=45 degree

2x=180-902x=90x=90/2x=45 degreeHence the value of x and y are 90 & 45 degre respectively
